It measures eighteen metres in diameter and rises to roughly one and a half metres in height, making it a substantial structure by any measure, though the surrounding trees have long since absorbed it into the general texture of the hillside.

A cairn of this kind is simply a mound of stones, typically raised over a burial during the prehistoric period, though the precise date and purpose of this one are not recorded. What is notable about its position is the specificity of its placement: not at the summit, as one might expect of a monument intended to be seen, but at a break in the slope, a point where the gradient shifts and the ground briefly levels. This kind of siting is not unusual in Irish prehistoric cairns, where the relationship between the monument and the surrounding landscape often seems to have been carefully considered, with the structure oriented or positioned to interact with a particular view, a particular light, or a particular moment in the movement across the land. The north-west orientation of the slope would have caught the late afternoon and evening sky.
